When diagnosing a master cylinder, keep in mind the type of seals that are used are lip cup seals. This design allows for the seal to improve as the pressure increases. Another feature of this seal is that it does not create a vacuum when the piston retracts.
Transmission shaft bearings with side-by-side arrangement together in a single mounting plate are known as “eyeglass bearings.” A defective twin-bearing mounting plate assembly shows no sign of damage on the outside. It usually makes a slight noise (e.g. whirring, rattling or grinding) while the transmission still operates perfectly.
Automotive technology continues to evolve in several directions. While many manufacturers are concentrating on electric and hybrid technology, higher mileage, and smaller and lighter vehicles, others are focused on performance, horsepower and ever-higher top speeds.
The Tiguan can be serviced about the same as the Jetta or Golf, but the vacuum brakes and EPS make the job a little different. The article goes over the Auto-Hold system, the correct pressure bleeding procedure, and what that creaking noise is.
These 10 tips will allow future alignment jobs to be completed more quickly and efficiently. This article reminds techs to check steering angle sensors, look at tire pressure before performing an alignment, and take notes.
The quickest way to solve electric fan-related, engine-overheating issues is to replace the entire cooling fan assembly as a unit instead of trying to repair or replace the individual fan motor. You’ll eliminate unnecessary steps, hassles and unbillable labor.
It may be possible to restore proper brake and steering operation by flushing the system. After cleaning, if the filter and fluid show obvious signs of hose contamination, all hoses must be replaced and both fluid and the in-line filter changed again.
Brake hoses are the most government-regulated components on a vehicle. Anyone making brake assemblies must be registered with the Department of Transportation (DOT). All aftermarket hose, fittings and complete hoses must conform to FMVSS 106 and SAE J1401. These tests are demanding and often exceed what a vehicle will see in the real world.
The trucking industry has a confusing term it uses called “wheel ends.” The term covers brakes, hubcaps, tires, seals, lubricant, bearings and spindle nuts. A 16 wheeler truck can mean more than 10 wheel ends units that can go bad. While the scale of these vehicles is rather large, the basics are the same when it comes wheel bearing diagnostics and maintenance.
What can you do in 17 minutes? You can make money on those 17 minutes of billed labor or you can give up those 17 minutes per corner of a vehicle in order to sell a more profitable part that has the potential to lower the chances of a comeback and give the customer more value for the money.
On different Mercedes-Benz models, you will see two types of TPMS systems. Low-line systems do not display individual tire pressures. These systems just monitor inflation and alert the driver if there is an underinflation or overinflation problem with one antenna. Mid-line systems display the individual pressures, and some systems have four antennas mounted near the wheel wells.
